What to expect

  • Upon arrival, you’ll find signage in front of the Center welcoming your child’s party. Neither you nor any of your guests will need to get in line.
  • You will be greeted by your party host who will assist with check-in, wristband you and your guests, sell any additional adult tickets you may need to purchase, and lead you to the private party room at the start of your event.
  • When arriving at your private party room, you’ll find:
    • The room decorated with wall theming per your theme of choice (LEGO Ninjago, LEGO Friends, or none) and non-allergenic permanently installed balloons.
    • The birthday child’s gift and birthday crown will be on the table at his/her birthday throne.
    • Colorful bins with LEGO brick will be placed on the tables for the build activity.
    • [Premium Party only] The children’s party favors (age appropriate mini-build kits) will be prepared for handing out at the end of the event.
  • The age appropriate build activity will be conducted by your party host first and will last 20-30 minutes.
  • At the end of the build activity, beverages (and pizza if you’ve purchased the Premium Party) will be served.
  • The last thing served is the cupcake cake. The party host will bring the cake into the room with candles lit so the party can sing happy birthday to the birthday child. 
  • Once the time in the private room is up, you will have the opportunity to store your belongings with us while in the Center or we can assist you in taking these items to your vehicle.
  • [Premium Party only] The guests’ party favors can either be distributed or stored until the end of your time in the Center.
  • You and your guests are then free to enjoy the Center for the remainder of your party after the hour in the private room is up. Typically, guests spend 2 hours in the Center after their time in the room. Your party host does not remain with you during this time and any additional beverages or food needed while in the Center are not complimentary.
  • If you wish, pick-up can take place in front of the Center where check-in/drop-off took place. Birthday parents generally communicate this to any parents who are just dropping off their children for the party.
